Few issues i need help with asap

I started completely from scratch because i was having problems with Slam. I deleted and re installed the domain, reinstalled wordpress then a fresh copy of the slam theme with the latest release. these are the issues I’m having
1) There is an error when i add an artist. i put the sreen shot.

2) I finally got the mix cloud to work but the album work does not show up on the home page or the music page. i have tried everything.

3) Last how can i remove the “Comments are Closed” in the bottom of pages?

Hi, something is totally not good in the server or installation, please send me access to info@qantumthemes.com I’ll check and fix, and send me also the FTP access so I can reupload the latest theme version with couple more bug fixes, thanks!
